TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, A'MORY F; SHERMAN, o'f Roxbury, inl the county ofNorfolk, and State of Massachusetts, have invented a new and useful Tiltor Tilting-Apparatus, for the exercise and'amusement-of children orothers; and I do hereby declare the same to be fully described in thefollowing specification, and represented in the accompanying drawings,of which- Figure 1 is atop View,

Figure 2 a sido elevation, and

Figure 3 a longitudinalsee-tien ofit.

The'main purpose of my invention is to cause the seats of a. tilt toremain in horizontal positions at Vwhatever angle of inclination thetilt may take -while inuse. In the drawings, A A denote two seats orchairs, fixed on the upper edges of two vertical boards, B B, suchbeards beingjoincd by means oi' two sets of parallel bars, C C, D,arranged against the ends of the boards,

and connected thcretoby screws or joint-pin s, as shown at a a, eachbar, at or neat its ends, beingso applied to the boards, and beingcapable of turning on such screw or joint-pin.

'.lhe several bars have notches formedwithin theirulowerl-edges, asshown at b b Ii, in thev drawings, such notchesvbeing to receive pins orscrews, e c, projecting from vtwo posts or standards. d d, extendingvertically from a base-board, e. m y

^ On the said. base-board there is placeda'dou'ble-inclined planefoot-rest, E, formed as represented in the drawings. A lseries of holes,fff, made inthe bottom boar-dg of the foot-rest, enables such -re'sttobo adjusted lengthwise, with reference to the chairs, and u pon studs7th extended up from the basetboard, such studs serving r to hold thefoot-rest in place on the base-board after any such adjustment ofthesaid foot-rest.

To the lower edge of each of the boards B B, an anti-concussion bufferor block or piece ot"-Indiarulxber,

or its equivalent', is fixed, the same being for the purposeof relievingthe tilt from the eil'ects of sudden jars,

when thestilt may bring up `against the bottom board of the foot-rest. Y

Thenotehes in the parallel bars are to enable the series -oithem, withthe chairs, to be moved on the s'upporting pins, so as to adjust theleverage tothe weights on'thechairs, when two persons ofdiiierentweights may be sitting on them. l

This tilt,` while in operation, willcause the seats or chairs 'tomaintain their horizontal positions.

What I claini as my invention, is-v l The combination ofthe tilt-seatsor chairs, and. a means, substantially' as' described, of maintainingthemin horizontal positions, while the tilt may be 'in action.

I also claim tho parallel tilting-hars, as made with notches, orequivalents, in thei'r 'lower' edges, as and for the purpose described.i

I also claim the arrangement and combination of the 4.adjustabledouble-inclined plane foot-rest, with the seats or lel1airs,and vthetilting parallel-motion bars and boards applied to such chairs andstandards, as explained.

`I also claim the combination and arrangement of the antifcon'cussionbuers with the tilt, as described.

AMORY F. SHERMAN.
